Supreme Court Blocks EPA Emissions Rule, Overturns Chevron Deference, Challenging Biden Administration’s Climate Agenda.

The Supreme Court has ruled 6-3 to block the U.S. EPA from enforcing its “good neighbor” emissions regulation, a rule aimed at restricting power plant and industrial pollution that travels over state lines. The ruling also overturned the Chevron deference, which originates in a fossil-fuel-related case 40 years ago. This could potentially delay or hinder efforts by the EPA to curb power plant emissions or FERC to develop new transmission lines. Two other rulings could invite more lawsuits over longstanding federal rules and make it harder for agencies to fine rule violators. The court’s conservative majority also ruled that a hedge fund manager facing Securities and Exchange Commission fraud charges was first entitled to a jury trial. These rulings are likely to pose a problem as the Biden administration continues to implement its climate agenda.
